SCENARIO EDITING DEVICE

PROBLEM TO BE SOLVED: To allow an external program to utilize, a scenario information stored in a device for editing the scenario information by adding extended attribute information to the scenario information when a time sequential flow of operation processes is expressed by a scenario constituted of a series of scenes. SOLUTION: A scenario information storing part 17 stores the constitutional elements of a scenario and the relation among the constitutional elements. An extended attribute information storing part 18 stores extended attribute information allowed to be dealed with by an external program correspondingly to the constitutional elements of the scenario. An extended attribute information updating part 15 executes edition processing for the extended attribute information stored in the storing part 18. A file output part 20 outputs edited plotting information, scenario information and the extended attribute information to a scenario file 5. A file conversion part extracts the extended attribute information from the file 5 and transforms the extracted information into a data format allowed to be dealed with by the external program.
